The folder path 'Epic Games' contains an invalid character?

Hi so recently my old hard drive failed with the game paragon installed on it so I got a new one and uninstalled the launcher and went and redownloaded it but when I go to run the installer it gives me the error listed in the the title so I don’t quite know what to do about this any help would be appreciated.

I was got same issue. It could be installed successfully if you delete all registr keys with ‘Epic Games’ keywords. I used ‘Windows 10 Manager’ utility.

yeah, its working for me… thx man!

Plz tell me how i can delete register keys plz help:(

  1. Press Windows + R buttons on your keyboard
  2. In appeared window insert command REGEDIT and press Enter. Will appear a new window of registry
  3. Press Ctrl + F
  4. In appeared window activate all flags and insert keywords Epic games and press Enter
  5. Delete registry entry you find
  6. Repeat steps 4 and 5 while the update will search for the entries

I can confirm that this worked for me too. Lots of registry keys to remove if you have many Epic Games installed.
